Some 75% of all companies using mainframes are in some way dealing with y2k, says a report by a subsidiary of Ziff-Davis, the publishing firm. Between 58% and 64% of companies using non-mainframe systems are working on the problem. This was as of summer, 1997.

These figures are higher than any other survey has reported. The sample was large: 31,000 sites.

As to what constitutes "solving their bug issues," the report's summary did not say.

CI conducted more than 44,000 interviews at organizations of various sizes in the United States from March to September, and narrowed the survey down to about 31,000 sites. Approximately three-fourths of businesses with mainframes were engaged in solving their bug issues.

But surprisingly, almost as high a proportion of smaller companies using proprietary midrange systems such as Digital VAX, HP 3000, or IBM AS/400s, without mainframes, had millennium bug projects — ranging from 58 to 64 percent over the three platforms.
